Effect of microemulsified collector on froth flotation of coal

Froth flotation is a fine particle separation process, based on the difference in surface hydrophobicity of different components. It is often very effective for coal cleaning, since coal is naturally hydrophobic and minerals are generally hydrophilic. Because of coal's hydrophobicity, froth flotation has employed mostly non-polar
